Opinion Essay
Many people say that taking care of the nature and making improvements on new technology is impossible, it is a big falacy, who say we need a lot of energy to produce materials. Well, let me remind you that with an amount of budget not big for goverments you can build wind parks and get the renewable energy of wind power or, if it is an area where there is not much wind, the other option is solar panels, even though this is not the best one, is one of the most efficient, and it can be placed on ceilings, streets, and open areas.
People say "no" to these options having as an argument that it is very expensive and that spending money on this is not worth at all. Scientists are developing new versions of these machines, although they are very expensive nowadays, but it will mean a change that will benefit next generations. Another convenient source of power is geothermal energy, but it can be found in some parts of the world, and Iceland is one of those lucky countries that has this energy, the only bad thing that this can cause is earthquakes caused because of collecting Earth's steam.

Sources of information
Alternative energy refers to energy sources that have no undesired consequences such for example fossil fuels or nuclear energy. Alternative energy sources are renewable and are thought to be "free" energy sources. They all have lower carbon emissions, compared to conventional energy sources. These include Biomass Energy, Wind Energy, Solar Energy,Geothermal Energy, Hydroelectric Energy sources. Combined with the use of recycling, the use of clean alternative energies such as the home use of solar power systems will help ensure man's survival into the 21st century and beyond.
From an environmental perspective, solar power is the best thing going. A 1.5 kilowatt PV system will keep more than 110,000 pounds of carbon dioxide, the chief greenhouse gas, out of the atmosphere over the next 25 years. The same solar system will also prevent the need to burn 60,000 pounds of coal. With solar, there's no acid rain, no urban smog, no pollution of any kind.
Wind Power:
Societies have taken advantage of wind power for thousands of years. The first known use was in 5000 BC when people used sails to navigate the Nile River. Persians had already been using windmills for 400 years by 900 AD in order to pump water and grind grain. Windmills may have even been developed in China before 1 AD, but the earliest written documentation comes from 1219. Cretans were using "literally hundreds of sail-rotor windmills [to] pump water for crops and livestock."
Solar Energy:
Solar energy is, simply, energy provided by the sun. This energy is in the form of solar radiation, which makes the production of solar electricity possible.
Electricity can be produced directly from photovoltaic, PV, cells. (Photovoltaic literally means “light” and “electric.”) These cells are made from materials which exhibit the “photovoltaic effect” i.e. when sunshine hits the PV cell, the photons of light excite the electrons in the cell and cause them to flow, generating electricity.
Wind Energy:
The moving air (wind) has huge amounts of kinetic energy, and this can be transferred into electrical energy using wind turbines. The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity. The electricity is sent through transmission and distribution lines to a substation, then on to homes, business and schools.

Mario Fellaini
Foresting S.A.
Valdivia
May 15th of 2014
Dear Mr. Fellaini,
I am writing this letter to you to tell that I'm very disgusted with the plans that your industry has, I can guarantee I am not the only one against this project. Sincerely the deforestation is a very bad business and it will give you a lot of problems in a not so distant future. The forests like the one you and your company are about to destroy are very rare and it will be an act of total inhumanity to turn that area into a condo of buildings, honestly it is unacceptable,
My first problem is that if you destroy this trees the ground will collapse, because the trees had been there for centuries and the soil is sustained with the roots of this trees, the ground will collapse and so your buildings.
In addition, if this place is destructed the regional nature park will have to close because of the low quantity of trees that they will expose and preserve, many people, elderly or young, frequent this place to have picnics or to take a trip with the family, it will be a shame if someone took everything from a day to another.
Furthermore, the fauna, if this green area no longer exists many endemic species or other animals will have no place to live, they will become very rare or even extinct, I will do not tolerate the fact that animals will day if this is made.
I hope you reconsider seriously this action that you are about to make, in benefit of Valdivia and the heritage of our country, keep the Valdivians forests.
Sincerely,
Juan C. Manriquez Benavides
